Epiphyseal plate
You have a primary cartilaginous joint between epiphysis and diaphysis. There is a plate of cartilage between the two. That make it possible for the bone to grow in length. This plate of cartilage is replaced by the bone tissue as the growth ceases.
Bones grow in length by endochondral ossification. It begins with cartilage that acts like a model of the bone that will grow. The bone grows in length and diameter(appositional). the structure that allows this is the epiphyseal cartilage that seperates the epiphysis from the diaphysis. When the bone is fully grown this cartilage will become bone and simply the epiphyseal line.
Meschyme (embryonic connective tissue) develops into a body of hyaline cartilage, covered with fibrous perichondrium, in the location of a future bone. For time, the perichondrium produces chondrocytes and the cartilage model growth in thickness.
epiphyseal plate
There IS a nose bone, in fact it's called the nasal bone at the top of the nose. It's a short bone that doesn't extend the length of the nose. At the end of the nasal bone is where the cartilage starts. You can find anatomical pictures on google for a visual.
trachae is lined by u shaped hyaline cartilages all through its length (from c6 to t4),the posterior free ends of the cartilage are bridged by the trachealis musle.
Long bones of the body, such as the femur, have an epiphyseal cartilage, a plate of cartilage that separates the epiphysis from the diaphysis as long as the bone is still growing lengthwise. An x-ray would indicate whether the epiphyseal cartilage is still present. The clinicians check if the cartilage is still there and if it is, growth is still occurring; if it is not, the bone has reached its adult length.
The primary ossification center is located in endochondral bones (the bones that form as a fetus is growing in the womb). It is in the shaft part of the bone (diaphysis), or the long, skinny part of it. Growth takes place in the epiphysial center of ossification. This primary ossification center is the key location for bone formation.
The epiphyseal plate is made of cartilage that forms at the ends of the long bones of the body. It is seen in infants and children. Once the child reaches adulthood, the plate has solidified into bone.

The function of hyaline cartilage is to provide flexible support. It has great tensile strength (due to the collagen) and is highly resistant to pressure (due to the ground substance). Hyaline cartilage provides a framework for the developing embryo prior to the appearance of bone. Later, it supplies the mechanism by which bones grow in length.
